naming variables through loop

[tefnut]

I need an x number of variables, say x=100 variables, so $var_1 to $var_100. Ideally I'd like a for loop, for ($i=1; $i<101; $i++), and have the variables be created, something like... $($i)=initial_value or $$i=initial_value.

How can this be done?

Or, perhaps there's another way to solve my problem. I have a list of ID's that I need to allow a user to select out of. So, I basically make checkboxes, and they check off the ID's they want. Then, when the information is posted, I made a loop to collect together the ID's that were indeed checked off. That's what I need this strange way of declaring variables, because I need to go through every checkbox, each of which has an individual ID that grows and therefore cannot be hardcoded. Any other way to do this, outside of checkboxes?

arrays....

$array[0]
$array[1]
$array[2]
$array[3]
$array[4]
...
$array[99]

for ($i = 1; $i <= 100; $i++)
	${'var_' . $i} = "";

But frankly it would be easier to use an array.
Just name the form element say, name="var[]"
Or you could use name="var[1]" to name="var[100]", to be more like your original proposal.

They can't be arrays 🙁

Basically I have this:

<input type="checkbox" name="$id" value="$id" />

Done from a database pull from an expanding number of ID's. Then, when this information is posted, I need a for loop to check every ID, so basically...

$list = "";
if ($1) { $list = $list."1, " }
if ($2) { $list = $list."2, " }
if ($3) { $list = $list."3, " }
.
.
.

That requires a for loop-ish thing, and that fact that I'm using for checkboxes prohibits using an array.

I can do that? :eek:

Thanks!
